It consists primarily of a welded steel frame, lighting system, a sealed transaxle motor drive system, electromagnetic braking system, electric motor controller, two batteries with an off-board charger and an adjustable seat.

It also includes a tiller handle for steering and a thumb operated potentiometer throttle control lever to engage and disengage the scooter motion in both the forward and reverse directions.

The scooter is powered by two 12 volt lead-acid DC batteries with 35.2 km (22 miles) with 36AH which maximum speed upto 9 km/hr (5.6 mph).

### Substantial equivalence:

The Bewell SC 20 scooter is substantially equivalent to the Be-Mobile 4-Wheeled Electric Scooter, DK S500 (K033239) manufactured by TUNG DENG ENTERPRISE CO., LTD.,

Analysis of comparison of design, function and feature of Bewell SC 20 scooter to TUNG DENG DK S500 (K033239), together with the results of compliance testing to existing ANSI/RESNA, ISO 7176 and IEC standards, demonstrate the device to be substantially equivalent to the predicate in terms of meeting performance criteria and functioning as intended.

While there are minor differences in performance specifications of the scooters, these differences do not alter the intended function and use of the device, nor do they raise any new questions pertaining to safety or effectiveness. Therefore, CHC believes that the Bewell SC20 scooter is substantially equivalent to legally marketed devices currently in commercial distribution.
